  abstract = {When developing a Service-Oriented Architecture (SOA), analyzing the
	business process is even more important than in normal software projects.
	Nevertheless, most of the requirements artifacts used in normal software
	projects apply to SOA-projects, too. This results in competing requirement
	models (like use cases and business processes) that duplicate information
	in parts. Even worse, these models are often contradictory, belong
	to different types of stakeholders, and need much effort to synchronize.
	However, these inconsistencies are an important source for requirements.
	We propose to deliberately switch between different views or perspectives
	to clarify them as soon as possible. In this way we a) enrich feedback
	and b) improve existing models as a by-product by confronting them
	with new perspectives. User interface mockups, data models, or business
	processes complement, enrich, and facilitate a pure use case perspective.
	We present a set of computer-supported techniques that leverage this
	friction between models and share our experiences in applying them.},
